Santorini has several beaches with a beautiful black sand due to the volcanic environment but not only. 

Further north from Kamari you will find many smaller beaches such as Vourvoulos, Baxedes, the Pori, Karterados and others.

Below Oia is Amoudi beach without sand and wonderfully secluded area for swimming and Armeni, which is located a little further to the south.

The end of the beach of Perivolos, for those who prefer more privacy is Ai Giorgis. A clean beach with black sand, walking for all, without umbrellas and sunbeds.

The continuity of Monolithos is the beach AVIS, or Exo Gonia. This beach is idesl to the wind surfers because it 's not protected from the air.
